Maritime Insurance Becoming Concerned About GNSS Disruption – Finally!

What’s new: The war risk insurance company for Norwegian ships is providing incentives for its customers to use Iridium A-PNT as a way of mitigating jamming and spoofing.

Why it’s important:

  • Insurance company concerns can often be as or more effective at causing an industry to do something than government mandates.
  • Other insurance concerns may decide to enact similar policies, or even require non-GNSS systems at some point.

What else to know:

  • This is a fairly limited use case as it is only for war-risk, Norwegian vessels, and involves the vessel getting the equipment and subscription in order to get the discount.
  • We hope the entire insurance industry across all sectors will become interested and involved in PNT resilience.
  • Saudi Arabia’s eLoran system serves the Strait of Hormuz, Persian Gulf, and the Red Sea’s Bab al-Mandab Strait. We have heard talk of one or more of those signals being used in a similar way.

Electronic signal interference is increasingly disrupting global navigation systems. GNSS jamming and spoofing incidents are rising across multiple maritime regions, putting vessel safety and operational integrity at risk.

What Can YOU Do? How Can YOU Help?

PNT is the quiet backbone of everything but too many leaders still don't see the risk.

But you do. You understand the systems, the dependencies, the failure chains. That insight is rare — and it's exactly what your country needs right now. Contact your government leaders and industry decision-makers and tell them resilient PNT isn't a feature — it's the foundation everything else depends on.
